I will never use this post office again. Paid for priority shipping, and extra insurance only to have the package not arrive by the third day. Dropped it off on the 8th of March before 11:00 am and my box didn’t leave Fort Sill until the 10th. My sisters Birthday is today the 11th. I’ll stick with the post office on 67 th from now on. They never fail me, was on post and thought to give this post office a try. Bad mistake.


I've been trying to get a hold of someone in your office with regards to a package that says it has been delivered yet the person has not received it. Who can I contact with regards to knowing who exactly it was delivered to??


Why have a phone number posted for a local post office if you never answer it? Do you not care about customer service? If I had the option to drive in your office I would, but I haven’t moved there yet.
